Hi, first time user of CasparCG. I’m trying to use my Ultrastudio HD mini card, but get the following error in server logs:

[struct caspar::tag\_msg\_info \*] = UltraStudio HD Mini [1-1|720p5000] Could not enable fill video output.

Here’s my config:  
\>

> ```
> <channel>
> <video-mode>720p5000</video-mode>
> <consumers>
> <decklink>
> <device>1</device>
> <embedded-audio>false</embedded-audio>
> <channel-layout>stereo</channel-layout>
> <latency>normal</latency>
> <keyer>external</keyer>
> <key-only>false</key-only>
> <buffer-depth>3</buffer-depth>
> <custom-allocator>true</custom-allocator>
> </decklink>
> </consumers>
> </channel>
> 
> ```

My Atem Ultrastudio is set to 720p50 in Decklink video software. Anyone know whats causing this error? Not getting picture on Ultrastudio from Caspar.

Have you tried with setting:

`<keyer>default</keyer>`

Does that give you any picture?

Still no picture with

```
<keyer>default</keyer>

```

More from the log:

A restart solved it. So config was correct, but I assume some settings to the Blackmagic box were not active before I restarted.
